The next in the Pretenders line is Splashdown, Autobot naval commander. His outer human shell resembles a deep sea diver, while his inner robot turns into an aquatic hovercraft. He was available in 1988.
The combined form of the Universe Micromaster Aerialbots is Superion, an amalgamation of six robots plus their pack-in accessories that serve as connectors, head, and extremities of the gestalt warrior. While in Japan, the original source of the design ( Sixwing , 1992) was available in a collected set, this combiner needed to be purchased one bot at a time in the 2007 Universe release.
